"Nick and Dum Dum," Steve explains. "I... wanted to find you. I figured SHIELD could help. The Avengers know; I filed a report for the team. The Fantastic Four would have access to that level of clearance of files, so they probably know. And two people who often work as my partner... the Falcon, and Diamondback." Steve realizes suddenly that Jack will need to know eventually, too -- but he hasn't had the frame of mind to look up other people who aren't always around.
